In June 2017, a man took a photograph up Gina Martin’s skirt at a music festival. The police told her that this was not a sexual offence; the man would not be charged. The law had let Gina down, and her first reaction was resignation. It’s too big, too scary, too complicated for someone like me to challenge this. I can’t do it. But something inside her had snapped. Gina was tired of accepting sexual harassment as a fact of life. Eighteen months later, she had changed the law and made upskirting a criminal offence. Now Gina wants to empower you with the tools and the courage to challenge injustice and fight for change. Whether it’s in your school, workplace or community, or even on a global scale, Gina’s practical and inspiring advice will ensure your voice is heard and your actions make an impact.
